webs with holes M to senire the desired socket member D and head E with their webs F and G. .Such piles may be driven in any usual or suitable way as by hammering or jetting. A jet pipe N for example, is shown located at the free edge of the pile of Fig. 1. After two or more piles haveI been driven a tight joint between them may be formed and the exposi'. metal may be further protected against corrosion by pouring or forcing grouteO into the space between the edges of the piles and the cavities adjacent to tlie metal interlocking members. To hold the grout, boards l may be driven along the faces of the joint. These will ordinarily be driven to a depth below the level of corrosion. This depth is ordinarily the lowest point at which the structure may be subjected to Contact of both air and water.

Fig. shows a form of the pile which departs from that of Fig. l in several details. The edge of the pile flat. The socket member is composed of two halves each consisting of a metal angle D with a web F embedded in the concrete. The metal head is the base E of a T, the web G of which is embedded in the concrete. The flanges F and G are punched. and tied together by tie rods or wires H', the free ends o'f which are held by simply bending before embedding them in the concrete. The reinforcement of the body of concrete consists in this case of vertical rods J, end wires or rods K', passing through the holes in the Web F and G, and side wires or rods K2 which may rest upon the end wires. This construction, and that of Fig. 6 hereinafter described has the advantage of using metal shapes of standard design which are manufactured by all mills, rather than the special shapes designed for the construction of Fig. l.

According to Fig. G there are used instead of the angles D members D2 of Z-shape which have not only webs F2 embedded in the concrete but also flanges F3 which give* a better attachment of the metal to the concrete. The ties between the socket member and the head member are the saine as in Fig. 5 and the reinforcement of the body of the concrete is the same except for the omission of the end wire K at thc socket end, the flanges F3 serving substantially the sa'me purpose.

Below the corrosion level it will not be necessary in all cases to extend the concrete. There are cases in which it would be necessary to extend only the metal members to`the extreme depth. For such cases a pile may be constructed with heavy metal members, such the head and socket members previously described, cxteinling below the base of the concrete. Fig. 7 shows such a construction. Tial concrete extends to a suitable depth below the Water line indicated at Q and the socket D and head E are continued below the bottom ofthe concrete. For embedding; in the concrete in tl-e ".ianner shown i.L the previ us figures the metal should be rolled rather light, the reinforcing of the concrete being its principal function, and being itself well supported by the concrete. For such use it is found that the lighter metal produces a better pile, one in which the concrete is less apt to be injured by driving. l/Vhere the metal is to be extended to a point below the concrete, where it is unsupported laterally by the concrete, I prefer that the extension shall be of heavier metal (or greater thickness or width). For such a construction, therefore, I prefer to use extensions D3 and E3 having the same internal contour of the socket and externalpcontour of-the head as for the members embedded in the concrete, but being in other respects of greater thickness. These heavier Ymembers may be fas tened to the projecting lower ends of the lighter members by splice plates It riveted or bolted upon the webs of the members.

Though I have described with great particularity of detail certain specilic embodiments of my invention yet it is not to be understood therefrom that the invention is restricted to the particular embodiments disclosed. Instead of making a single style of pile with a head at one edge and a socket at another two styles of pile may be used, one having heads at both edges and the other having corresponding sockets at both edges.

Various other Changes may be made in detail and in the arrangement and combination of the parts by those skilled in the art without departing from the invention.

What I claim is:

l. A composite sheet pile comprising a concrete monolith with exposed concrete faces and having longitudinally extending tongues and grooves on opposite faces thereof, metal interlocking members embedded in the tongued and grooved faces of the concrete, and ties embedded in the concrete connecting the interlocking members atV separated intervals in the length thereof, said interlocking members having means Whereby to hold adjoining piles in interlocking engagement.

2. A composite sheet pile comprising a concrete monolith with exposed concrete faces and having the web portions of metal interlocking members embedded in opposite faces of the concrete, and metal ties embedded in the concrete securing said interlocking members together at separated intervals in the length thereof, said interlocking members having means whereby to secure the adjoining edges of adjacent piles in interlocking engagement.
